Getting System.ComponentModel.Win32Exception : Access is denied on using ControlSend to send keystrokes in dialogs

Hi, 

Getting System.ComponentModel.Win32Exception : Access is denied on using ControlSend to send keystrokes in windows/os generated dialogs

Piece of code I am using is this:

sleep(5000)
WinWait("[CLASS:Chrome_WidgetWin_1]","","20")
ControlSend("[CLASS:Chrome_WidgetWin_1; Title:Document Retrieval - OnBase 25.1.0.221 [Unknown] - Google Chrome]", "", "[CLASS:Intermediate D3D Window; INSTANCE:1]", "{TAB}")
ControlSend("[CLASS:Chrome_WidgetWin_1; Title:Document Retrieval - OnBase 25.1.0.221 [Unknown] - Google Chrome]", "", "[CLASS:Intermediate D3D Window; INSTANCE:1]", "{Enter}")

I need this to handle a dialog that comes from a service and my job is to click on one button and remove it from focus. Also most importantly i need to run this code via jenkins in a remote vm where my automation tests run.

Sharing a screenshot of the AutoIt v3 and the dialog that i want to handle:
